C# Webmatrix/Razor-问题返回正文

我正在尝试为webhook响应编写一个快速页面。该方法需要获取查询字符串参数，并在主体中传回响应。这是我到目前为止所拥有的

@using System;
@using System.Collections.Generic;
@using Braintree;
@using System.Diagnostics;
@{
    Layout = "~/template";

    //Initialise Braintree Server SDK
    BraintreeGateway gateway = new BraintreeGateway
    {
        Environment = Braintree.Environment.SANDBOX,
        PublicKey = "xxx",
        PrivateKey = "xxx",
        MerchantId = "xxx"
    };

    return gateway.WebhookNotification.Verify(Request.QueryString["bt_challenge"]);

}

问题是，当我运行此页面时，会收到以下错误消息：

由于“ASP.\u Page\u Payments\u Webhook\u cshtml.Execute（）”返回void，因此return关键字后面不能跟对象表达式

虽然我不熟悉您尝试执行的所有操作，但我认为cshtml页面不应该返回任何内容，因此警告是这样的。所以，除了最后两行代码外，请完全按照您的代码进行尝试。取下回流管，改为：

@using System;
@using System.Collections.Generic;
@using Braintree;
@using System.Diagnostics;
@{
    Layout = "~/template";

    //Initialise Braintree Server SDK
    BraintreeGateway gateway = new BraintreeGateway
    {
        Environment = Braintree.Environment.SANDBOX,
        PublicKey = "xxx",
        PrivateKey = "xxx",
        MerchantId = "xxx"
    };


}

@gateway.WebhookNotification.Verify(Request.QueryString["bt_challenge"]);
